The couple is already parents of a child, son Mateo, who was born in January 2015.

At the time, the actor and director said in a statement,

I believe he is mine. We are all thrilled to welcome him to this cold, cruel world. We are all thrilled that he is here and healthy.

Stanley is also a father of three other children with his late wife Kate Tucci, who had died of breast cancer in 2009.

Stanley and Felicity were also joined by her younger sister, Emily Blunt, on Thursday night, which turned into a Devil Wears Prada reunion which was became possible with the attendance of Meryl Streep.
